For Reaction Creators
Turn reaction streams into
clips that keep your face
A reaction clip is worthless if you crop out the reaction. Nova stacks your facecam over the content you're reacting to — your face up top, the video below — in one vertical 9:16 clip, finds the biggest moments, and captions them, so the reaction and what caused it land together.

Keep the reaction in frame
Nova detects your facecam and stacks it over the content — your reaction on top, the source below — instead of a single crop that throws away half the clip.
It finds the peak reactions
AI scans the whole VOD for the moments that pop — the laughs, the shock, the hot take — so you ship highlights instead of scrubbing hours of footage.
Vertical and captioned, no editor
Every clip exports 9:16 with word-by-word captions burned in — ready for TikTok, Shorts, and Reels straight out of Nova.

Questions? Answers.
Does Nova keep my facecam in reaction clips?
Yes — it auto-detects your webcam and stacks it over the content in a vertical layout, so viewers see your reaction and the source together. If auto-detect misses, you can set the facecam corner manually.
Where can I clip reactions from?
Upload a recording or paste a YouTube or Twitch link. Nova processes the footage and surfaces the strongest reaction moments automatically.
